"Company repaired the issue in less than a week from contact. Appreciative of that. John was friendly and repaired the issue in a timely manner. Seems like there was some confusion in the beginning on the details of the project; maybe initial details from Angi’s wasn’t shared with the company. The company and I worked through that on the initial call which was fine. I am suggesting that maybe to confirm companies get the request info provided by the customer on the Angi site. Thanks for providing this service for repairs."

Len The Plumber, LLC. is a leading plumbing and drain company serving Central Maryland. Our certified professional plumbers are available same day to assist residential customers in Anne Arundel County, Baltimore City, Baltimore County, Carroll County, Cecil County, Harford County, and Howard County. Our knowledgeable plumbers have years of experience dealing with a wide variety of plumbing issues including plumbing repairs, drain cleaning, water heaters, well systems, heating systems, sewer, water, and gas lines. We’re open 7 days a week with no extra charge on evenings or weekends!

"I’ve used Len the Plumber in the past, but after today, I will never be using their services again. I called to follow up on a recent (and expensive) drain repair - work that my family stretched our budget to afford. The plumber who came out was great: professional, kind, and respectful. But unfortunately, the drain is still not fully cleared. When I called customer service to ask if there was any warranty or guarantee on the repair, I was met with nothing but attitude. I wasn’t rude, I simply asked a question. Rather than receiving a straightforward answer, I was spoken to in a condescending and dismissive tone, as if I didn’t have the right to inquire about a service I paid a significant amount for. If the answer is “no, there’s no warranty,” then just say that. I would’ve scheduled another appointment and paid for the additional work. But I refuse to support a business that treats its customers like that over the phone. I hung up and blocked the number. To whoever runs this company: please take customer service seriously. It’s hard enough to pay steep prices for plumbing work—being treated rudely on top of that is unacceptable. Hire people who are kind and respectful to your customers. You’ve lost my business."

FAQs for tankless water heater installation projects in Bel Air, MD

Professional flushing services for tankless water heaters run about $200 per visit. This essential maintenance procedure eliminates mineral deposits from critical components, particularly the heat exchanger. While homeowners can purchase DIY flushing kits for $50 to $100, professional service offers the advantage of thorough cleaning with proper techniques. Professional maintenance also includes inspection of additional components that might need attention.

Industry experts and manufacturers recommend annual maintenance for tankless water heaters, with more frequent service (every six months) for homes with challenging water conditions. This regular attention prevents efficiency losses and extends the unit's operational lifespan. Watch for warning signs like reduced water temperature, inconsistent performance, or system error codes that might indicate maintenance is needed sooner than scheduled.

Neglecting regular maintenance allows mineral scale to accumulate within your system, restricting water flow and reducing heating efficiency. This forces your unit to work harder, consuming more energy while delivering less satisfactory performance. Over time, this strain can lead to component failures, inconsistent water temperatures, and premature system replacement. Additionally, most manufacturers require documentation of regular maintenance to honor warranty coverage for major components.
